Application tiled March 2', 1903.

Be it known that we, MAXIMILIAN KLAI- BER, ofthe berough'of Brooklyn, county of Kings, and IRVING' G. MoCoLL, of the borough ofManhattan', coun-ty of NewYork, city and Slate of New York, citizens of the United States, have invented an Improvement; in Storage Flash-Lamps', of which the following is a specification.

Heretofore in the employment of lamps for flash-light photography difficulties h ave been experienced in diffusing the light so as to get the benefit of all the' rays, also in an effort to burn all of a given' charge of powder t`o the best advantage, andalso in means for charging the lamps with -burningiiuid so that none is wasted or spilled over the lamp.

Iii-carrying out our invention we employ a structure adapted for producing a relatively thin or narrow lameiof substantially semicircular or fan -shaped form vertically disposed, devices delivering the flash-powder in a thin-stream or layer of corresponding form and directing the same into the entire mass of flame, and devices when the lamp is turned in anl invertedA position which receive the burning fluid and direct the same to the wick or other absorbent material of the reservoir,

so that there is' no liability of the burning iiuid coming into contact with thepowder-deliverng devicesl Y In the drawings, Figure 1 is a vertical central section Fig. 2, an 'elevation and partial section at theline uw of Fig. l; and Fig. 3 a plan, partly broken away, said figures illustrating the approved form of our invention; and-Fig. Ltris a vertical central section representing a slight modification and illustrating the semicircular form of our invention.

Referring to Figs.- l, 2, and 3, a is a reservoirforthe flash-powder of tubular form,

preferably provided with a removable screv'v-4 cover ct and at its lower end secured to the' base or support-b, which preferably is provided with a raised portion b', entering the lower end'of the reservoir@ for an appre-v `brought to the reservoir o.

absence of the handle the screw of a tripodtop may be secured to the socket b2, and the ilash'- lamp instead of 4being carried in the hand by means ot' the handle lc maybe supported upon a tripod. Connected with one side of the reservoir u, near its lower end is atubef2 with an irregular surface, and whichY tube is adapted to receive around it a rubber tube through -'which air under pressure is We prefer that the lower portion of the bore of the tube 2 be made on'the saine plane as the upper surfacek of the raised portion b of the base, and from the opposite side of the reservoir a extends the delivery-tube 3. This deliverytube we prefer to place in the same axial line as the tube 2 and to make the aperture ot' said tubethat is, the exit thereinfrom the reservoir ct of smaller interior diameter than the interior diameter of the tube 2, andthis for the purpose of accelerating the discharge of the dash-powderA from the reser- The delivery-tube 3 is at its free end preferably made with a semicircular turn and the nozzle or orifice 4 as an arc of a circle in cross-section, as shown in Fig. 2. The delivery-tube 3 is of considerable strength and serves as a support for the reservoir of burning fluid-and the devices connected land direction to the delivery ot' the iiashlpowde'r. 1 In forming the receptacle for burning fluid .we 'prefer to bend-a sheetfof metal so as to @provide a plate c witha semicircular edge, and a plate c', having parts at right angles to one another, and between which plates there is a curved base 'or oonnectingvportion, the bend of the plate o' producingan edge and the ends of the parts beingprovided with return- .bends= 6, that are connected, so as to form in ,this manner a receptacle with fluid-tight 1 joints.

We provide a semicircular plate g,

connected along a base or straight edge to the Aedge'or angle 5 of the plate c', said, plate lyling'parallel with the plate o and forming a substantial prolongation of the portion of the plate c', that is also parallel to the plate c in forming the receptacle for burning Huid. This plate c' is oi considerably smaller radius than the plate c. The plate o is made with a curved edge c2,'the curve being toward the IDC plate g, and the absorbent material CZ, which is preferably wick or absorbent cotton, is packed in between the plates c and g, following the curved outline of the plate g, and also is packed in between the plates c and c at the curved base or connecting portion, and the same may be held in position in any desired manner. The outer edge of the plate o is preferably curved, and at the central portion the same is securely connected to the semicircular end of the delivery-tube 3, so as to form a permanent connection and cause the said parts to be supported by the deliverytube. We provide a deiector-plate e, of semicircular form, as shown in Fig. 2, and the edge of which is secured to the face of the plate g, and this deilector-plate e is of tapering form, as shown in Fig. 3, and the other edge thereof is secured to the plate c', so that the configuration of the plate ein Fig. l with reference to the connected adjacent portions of the plates c and g is the form of a rightangled triangle. The pointed forward end of the deflector-plate e (see Fig. 3) preferably extends under the nozzle 4 of the deliverytube, and a cover-plate j", also of semicircular form, is fastened to the plate c at its lower edge, extends over and is fastened to the delivery-tube 3, and its free edge is in a plane parallel with and adjacent to the surface of the plate g, its edge being slightly above the upper edge of the said plate.

We have shown and prefer to provide posts Zt h', secured to the base ZJ at opposite sides of the reservoir a and which posts are preferably higher than the level of the upper surface of the delivery-tube 3, and the upper portions of these posts are notched to the level of the delivery-tube, and in said notches we prefer to secure a bar Z and to impart thereto a curved form. Said bar extends between the posts forward of the reservoir a and is secured to said posts, said bar at its ends occupying only a portion of the notches of the posts Zz h'. The notches of these posts are employed for receiving the lower ends of a reflector Z', which may be of cardboard, asbestos, metal, or any suitable material having a white or light-colored reflecting-surface. The said posts and bar Z make it possible to maintain a curved form imparted to the reflector Z', and at the central point said reflector preferably bears upon the reservoir a, and we prefer to employ on the back of the semicircular plate c and at opposite ends sockets having adjustingscrews m m', which screws come against the outer surface of the reflector Z, contacting therewith and according to their position holding the reflector in its curved form and adjusting the same, so as to permit the reector to be vertical or to be tilted slightly forward or backward.

In the modified or simpler form of the invention, Fig. 4t, the parts c, c', c2, e, f, g, 3, and 4 are the same and perform the same functions as parts bearing the same letters of reference in the other gures. The device,

Fig. 4, is not only simpler but less expensive to construct than the device of Figs. l to 3, inclusive. In this simpler form d2 is the reservoir, open at the upper end, of conical form, and at its lower end connected to and emerging with the 'delivery-tube 3, the outer end of which is preferably roughened to directly receive thereon the end of a rubber air-tube.

In the operation of the device the lamp is to be turned over, so that the plates c g occupy a horizontal plane. In this position the alcohol or other burning fluid is poured directly upon the plate c, the curved edge c2 preventing the material escaping and acting as a lip to retain the burning fluid and compel the same to flow toward the absorbent material CZ, which takes up the same. When the absorbent material is sufficiently charged with burning fluid, the lamp may be turned into the position shown in the drawings. The reservoir a is then charged with the desired quantity of flash-powder andthe burning fluid then lighted. The semicircular form of the plates c g compels the flame thus produced to be also of semicircular or fan-like form, vertically disposed, and necessarily of thin and extended area. Air under pressure is forced through the tube 2 into the reservoir and impels the flash-powder from the reservoir through the tube 3, and as this flash-powder is delivered from the curved orifice of the nozzle 4 the powder is spread and delivered against the deflector-plate e, which further spreads the powder, and the force irnparted to the powder as delivered is sufiicient to carry the same over the surface 0f the plate e, up the flat surface of the plate g, and through the opening produced by the juxtaposed edges of the plates g and f. The position of the plate fand the fact that the upper edge thereof extends above the edge of the plate g acts to direct this flash-powder into the flame. In this way the powder may be delivered by air impulses, and as delivered is formed into a thin layer and all discharged into the wide expanse of flame to be consumed and produce a flash-light of great intensity, the thin semicircular stream of air as delivered with the powder also appreciably increasing the semicircular area of the flame for the production of the best results. Su bstantially the same operation is performed by the employment of the simpler form of our device illustrated in Fig. l; but it will be noticed that this device is of less expensive construction, that there is no cover provided to the hopper, and that the nozzle 4 of the delivery-tube is of the same area as the delivery-tube. Consequently theorificehere will be made circular instead of curved, as in Figs. l to 3, inclusive, and while we obtain the best results from the device, Figs. l to 3, inclusive, We do obtain very satisfactory results from the employment of the simpler form of the invention, Fig. 4. In this simpler form the flash-powder as delivered IIO from the nozzle `or orifice-4L is spread by the' defiector-plate e, and in filling the lamp of this forni with the plate c in a horizontal position the same non-spilling function with reference to the burning fluid is obtained as Vin the device of Figs. l to 3, inclusive.

Referring to Fig. 3, it will be noticed that as between the back of the plate c and the forward surface of the reflector Z there is a space which it is found in practice is sufficient to establish arising current of air while the fiame is burning, which has the function of increasing the area of the dame to an extent that is greater than if the reflector Z is absent. This extension of the dame for this Vreason increases the illuminating area when the dashpowder is blown into the flame, increasing the light area and so producing better results, and this space is regulated by means of the thu rnb-screws m fm'.
